The Lumex 5590R-SLB-1 and 5590R-SLW-1 are high-quality elastic shoe laces designed specifically for individuals with limited mobility. These laces turn any lace-up shoe into a slip-on, allowing users to put on and take off their shoes without bending or tying. They provide enough tension to keep the shoe secure on the foot while stretching enough to allow easy entry, making them an essential accessory for post-surgery recovery.
